Abstract :
The fiber-optic sensors generally need to be packaged for practical applications. Carbon fiber composite is an excellent package material due to its light weight, high toughness, ultrahigh Young´s modulus (with tensile modulus of 420 GPa or more), good environmental resistance, etc., and it has been widely used for the aerospace and automotive fields. Here, we demonstrate our recent research achievements of embedding the FBG and photonic crystal fiber sensors in the carbon fiber composites for temperature-insensitive and intensity-modulated microdisplacement measurement.
